Description:

Abstract:: North American Continent coastlines, international boundaries. Comprehensive 1:15,000,000 scale vector basemap consisting of cartographic, attribute, and textual data. The source of this data include ESRI data at 1:15,000,000 and 1:3,000,000 and NIMA DCW data at 1:1,000,000. The larger scale data has been generalized to approximate 1:15,000,000 scale.
Purpose:: Base map for general Geographic Information Systems applications. This shapefile contains very small scale (1:15,000,000) national and state/province boundaries for North America.
